1 Be it. known :that- I,- @RALPIT .H'QROSENBERQ,

a; citizen of the United States, and a resident-of Columbus, Ohio, haveinvented f cer- V tain new i and useful Improvements :inIDriving-Gearing for Motor-Vehicle's, of which the following is aspecification. a

hsMy:inventionrelates to improvements in automobiles and hasparticular rf e t l 'g axles forsuch vehicles. {Y

The object ofmy lnvention 1s to-zlessen the first-or manufacturing costto reduce the labor. required for assembling 'and disas sembling theaxlesvand. frame ofthe automobile andjto' provide a driving axle, parts,

of which can-:be interchangeably usedf with either steering-ornon-steering wheels."

A further object 'of my inventionis toprovidean' axle which willfacilitate inspection and repair of the differentiali'mechanism whichforms apart-thereof. r

VA further object of my invention is to provide a driving axle so formedand con ne'o'te'd to the vehicle thatthe power transmitting partsthereof. can be [easily-* and quickly removed and replaced Iwithout dis1 connecting or disturbing the load carrying springs. v A

' Y My invention consists in the combination ofparts by which the aboveand other objects are attained and all ashere nafter describedandpointed out in the claim.

'My invention. will be readily understood by reference to theaccompanying drawing,"

the view thereof illustrating a longitudinal central section of themlddleportion of my improved axle, and'mecha'nlsm and frag- I ments ofshafts therein contained, the latter being in full lines. 7

I an end section 10 at each end thereof. The

end sections lO'may, if desired and aswell understood, beformed forconnection withwheels which are driving only, or for connection withwheels which are both driving and steering wheels. The inner ends of theend sections are provided with circumferential bolting flanges 14 andthe center sec sp m aqn m r m- Patented Dec.21,'1915. Application filedFebruary 14, 1912;?

t i'ons are long enoughto-fill'in between the opposed boltingflangesv ofthe end sections. The center sections 9 are always substantiallyidentical and each thereof is provided on its ends with boltingfianges15 which are companion to thezbolting flanges carriedby the end;sections and the center sections-are bolted to the end sections by means.of a plu ralityv of clampingbolts. 1 6 which pass through both of'theflanges. Inrorder-to maintain; the center and end, sections in properali'nement, the-36nd sectionsare provided with dowelingsflanges 17whichproject within the outer ends ofjthe center section. I The centersection of the axle carries within the gear casingthedifferentialgearing 18. In the drawing I haveiillustrated this: differential.gearingasbeing-what may a be termed a'w'ormwgear differential which isin-.

closed. inthe housing or casing19 forming.

part .ofthe'center section 9 ofthe a-xlefi This. differential gearing,as illustrated consists of *a pair of opposed 'bevel'wheels 20 mountedinbearings 21 in the casing 19, a worm wheel 22' centrally mounted inrelation to said bevel wheels and carrying a pair of bevel wheels 23mounted on radial bearing pins 24 and meshing with the bevel gears 20.The wormwheel is driven by means of a worm 25 mounted in bearings in theupper part of the casing 19 and connected to the engine through ahorizontal shaft 26 which is provided with suitable universal joints 27.The bevel gears 20 are provided with square centrally arranged openings28 for receiving the inner ends of the driving aXles 29. The casing 19is provided with a transverse flange or partition 19 which closes thecenter or gear containing portion-at each end and each thereof isprovided with an opening 19" in central alinement with the square 7opening 28 in the hub of the adjacent bevel wheel 20. This opening isslightly larger than the inner end of the driving shaft 29 and serves toguide the end of this shaft when it is being entered into the squarehole in the hub of. the bevel wheel 20. These shafts extend'outwardlythrough the hollow axle and are suitably connected with the driving orroad wheels (not shown). The worm wheel 22 is mounted or carried upon acentrally arranged sleeve 31 which extendswithin and is carried by thebevel wheels 20. Th s 51. 6% contacts at each end with a shoulder 32within each bevel wheel and the bevel, wheels are prevented fromseparating by the bearings 21 against" which they contactziirdWithinwhich they are mounted. This. construction permitsthe drivingshafts 29 to be removed from the axles'or hoiisings without disturbingthe relation of the vari- 7 oils" parts of thedifi'erentia'l'"mechanism. In other words, the shafts canbe-withdrawn.
